Trick of Fate

Kotoko, from the lowly F-Class, has a crush on Irie, who is the top-ranked student from A-Class. After two years, she collects her courage and confesses to him and tried to give him a confession letter, only to be bluntly turned down. Irie even goes so far as to say he hates stupid girls (meaning her) and doesn't even read her confession letter. When an earthquake strikes Tokyo, her house is the only one damaged. A friend of Kotoko's father jumps at the opportunity to lend a hand, and in a surprising turn of events they end up living at Irie's house.
